JOHN LINES, OF WATERBURY, CONNECTICUT, ASSIGNOR TO THE SCOVILL MANUFACTURING COMPANY, OF SAME PLACE.

BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 593,401, dated November 9, 1897.

Application filed July 20, 1896. Serial No. 599,814:- (No model.)

T0 (0% whom, it may concern:

Be it known that I, J OHN LINES, of Waterbury, in the county of New Haven and State of Connecticut, have invented anew Improvement in Bottle-Stoppers; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

Figure 1, a view in side elevation of a plug or stopper constructed in accordance with my invention; Fig. 2, a sectional View thereof; Fig. 3,'a detached view of the body of the plug before the cutting of the threads in its rib.

My invention relates to an improved stopper or plug for hot-water bottles and kindred vessels, the object being to produce at a low cost for manufacture a strong and effective device of a neat and attractive appearance.

\Vith these ends in View my invention consists in a plug or stopper having certain details of construction, as will be hereinafter described, and pointed out in the claim.

In carrying out my invention I form a plug by performing the required operations upon a sheet-metal blank of cup form, the blank being drawn, struck, or otherwise treated, so as to form a cylindrical body A, having its lower end open and its upper end closed and provided with an overhanging integral flange A, which is larger in diameter than the diameter of thelbody A, and which is formed by folding a portion of the metal of the plug upon itself. The central or waist portion of the body is provided with screw-threads A which are cut into an annular outwardly-projecting rib A struck outward from the body and shown, before it is threaded, in Fig. 3, which shows that the shoulder formed by the upper edge of the rib is well separated from the under face of the said flange A and that the shoulder formed by the lower edge of the rib is well separated from the open lower end of the body A of the plug. A body so formed is provided with a handle B, which may be of wire. as shown, or of sheet metal. It is applied, as shown, by forming perforations a a in the body, inserting the ends of the handle thereinto and riveting or heading down or otherwise securing their projecting inner ends, as clearly shown in Fig. 2.

I would call attention to the fact that the metal of which myimproved plug is made is of uniform thickness in the finished pl'ug,except for the portions of the bead which are cut away by threading. I wish also to point out the extreme simplicity and strength of my device, and also to point out that on account of its construction it is peculiarly well adapted to be kept clean.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A stopper or plug for hot-water bottles and the like, comprising a sheet-metal body of uniform thickness except where threaded,

JOHN LINES.
